Patented Oct. 11, 1938 PATENT OFFICE CLOSURE FOR. SEALING BOTTLES AND LIKE RECEPTACLES Fernando Casablancas, Sabadell, Spain Application August 26, 1936, Serial No. 98,032 In Spain August 30, 1935 4 Claims.

The present invention relates to closures for sealing bottles and like receptacles, which are applied exteriorly on to the mouth of the bottle or the like and has for its chief object the provision of an improved stopper which will permit of the sealing and unsealing the receptacle a great number of times, while always affording a perfect hermetic seal.

The closure according to the invention comprises essentially a metal cap inside which is disposed an elastic member having a number of curved lugs, the said elastic member being combined with an eccentric actuated from outside by means of a lever, whereby the elastic lugs engage a flange disposed exteriorly on the neck of the bottle, a hermetic seal being obtained by the interposition of a washer or disc of rubber 'or other suitable elastic material between the said member and the mouth of the bottle.

The action of locking the curved lugs in order that they may engage on the flange oi the neck of the bottle is obtained by the special arrangement of the outer cap of the closure, which has a conical portion fitting on the curved part of the lugs, the whole being so arranged that upon actuation of the eccentric the elastic member is forced into the cap, the pressure of the conical portion thereof thus bending and locking the lugs of the elastic member. Subsequently, in order to withdraw the closure from the bottle, it is suflicient to actuate the eccentric in the opposite direction, whereupon the pressure acting on the elastic lugs is relieved and the lugs leave the flange of the bottle.

A form of construction of the closure according to the present invention is illustrated in the accompanying drawing, in which:

Figure l is a sectional view of the closure in the position in which it is mounted on the bottle.

Figure 2 is a section of the closure fitted on a bottle.

Figure 3 is an exterior view of the closure fitted on an object of suitable dimensions and form for placing on the market, and

Figure 4 shows a modification.

The closure is constituted by a cap "I subdiscs l5 and I6, connected together by rivets or other suitable means, and the upper disc I5 is in turn connected to a U-shaped member H, which projects upwards and traverses the upper part of the cap projecting to the outside.

In the extremities of this U-shaped member there is disposed a spindle or pin l8 serving as a pivot for an eccentric I9 connected to a lever 2|! and so disposed that upon actuation of the said lever the eccentric bears against the upper part of the cap I0, preferably through the intermediary of a washer 2|, and lowers the cap III in relation to the elastic member l2, thus causing the lugs of the said elastic member to become locked by their engagement with the conical surface II and, consequently, to engage firmly on the flange 22 of the neck of the bottle or receptacle 23.

Furthermore, in order to obtain hermetic sealing, there is disposed between the elastic memher and the mouth of the bottle a washer or disc 24 of rubber or other suitable elastic material, which is normally held in position in the stopper by the same curvature of the elastic lugs.

In the modification shown in Figure 4, instead of the full rubber disc 24 of Figures 1 and 2, there is employed a rubber washer 30 which in its central part bears a cup like piece 3| of aluminium or other suitable material. This arrangement prevents the liquid in the bottle from touching the rubber, but in other respects is fully equivalent to the arrangement of Figure 1.

The lever 20 actuating the eccentric may be of any desired form, preferably curved, as shown in the accompanying drawing in order that once the bottle is sealed this lever may flt against the neck thereof without causing any obstruction. Moreover, in the said lever there is also provided a recess 25 of suitable form, one of its edges 26 being slightly bent over in order that the said recess may be used for opening the receptacles or bottles sealed by the closure.

Finally, this cap may be combined with an object of suitable form, for example that shown 4 in Figure 3, which has the form of a small receptacle, the upper part of which has the usual dimensions of the mouth of a bottle. This object serves for the presentation of the closure for sale in attractive form and may be so disposed that, in addition, it may then be used as a tooth-pick holder or for other purposes.

I claim:

1. A closure for a container having a flanged opening, comprising an elastic grasping member having an upper portion and depending lugs, a cap over said member having upwardly tapering side walls and an opening in the top, a rod extending from said member through the opening in said cap, means for securing said rod to said member, and cam means at the free end of said rod for urging the cap downwardly toward the member whereby the tapering side walls move the lugs inwardly to engage the flange of the container.

2. A closure for a container with a flanged opening, comprising an elastic grasping member having an upper portion and depending lugs, a rod attached to said upper portion and extending upwardly therefrom, a cap having an opening in the top to receive said rod and having side walls at the bottom of greater diameter than said lugs and an upwardly tapering portion of less diameter than the lugs, and cam means pivoted to said rod above said cap adapted when operated to work on the upper side of said cap and force it downward upon said member whereby the tapering portion of the side walls of the cap urge the lugs inwardly to engage the flange of the container.

3. A closure for a container with a flanged opening, comprising an elastic grasping member having an upper portion and depending lugs, a

rod secured to said member and extending upwardly, a cap having an opening in. its upper wall to receive said rod and having side walls of a diameter to force said lugs to engage the flange 01' the container when the cap is positioned around said member, and a lever pivoted at the free end of said rod above the upper wall of said cap, said lever having a cam portion to work against the upper wall of the capwhen the lever is operated to draw the cap and member together and position the cap around the member.

4'. A closure for a container having a flanged opening, comprising an elastic grasping member having a flat upper portion and depending incurved lugs, connected discs above and below said flat upper portion, an upwardly extending rod secured to the disc above said portion, a cap over said member having in its upper wall an opening to receive said rod and having upwardly tapering side walls, and cam means secured to the upper end of said rod above said cap adapted when operated to work on the upper wall of said cap to force it toward the member whereby the tapering side walls move the lugs inwardly to engage the flange oi the container.
